Hirschmann MTM2800-PSU120 Technical Review for Maintenance Engineers, Integrators and Procurement Teams
Confirm the exact rack-switch identity
Hirschmann MTM2800-PSU120 identifies the Hirschmann modular Ethernet switch power supply, model MTM2800-PSU120, part number 942999840. Keep the complete model and part number in the RFQ because nearby MTS and MTM variants may differ in access ports, uplinks, PoE budget, airflow, power supply, software features or chassis role.

Build the port and uplink schedule
The saved manufacturer record lists the interfaces stated in the manufacturer record. Map copper, fiber and high-speed uplink ports to the network design before ordering. Confirm transceiver type, fiber medium, link distance, breakout needs and spare-port allowance instead of selecting a rack switch from the nominal port count alone.
Review power, cooling and installation
The source gives 100-240VAC, an operating reference of -10-+55 °C, and dimensions of the documented chassis or module dimensions. Check rack depth, front-to-back airflow, fan or PSU redundancy, grounding, branch protection and cable clearance. For PoE models, calculate the powered-device demand and reserve rather than assuming every port can deliver the maximum load simultaneously.

Separate chassis and field-replaceable items
Some MTM references are power, fan or modular system components rather than complete switches. Ask the quotation to identify exactly what is included and list chassis, power supplies, fan modules, interface modules, licenses and transceivers as separate line items when they are not part of the stated supply.
Prepare a procurement-ready RFQ
Send HKXY the exact reference Hirschmann MTM2800-PSU120, part number 942999840, quantity, destination and required delivery date. Include the rack elevation, port map, power-feed design, airflow direction, software or management requirements and required approvals so the response remains tied to the actual project configuration.
Acceptance and lifecycle record
At receipt, compare the delivered label with the approved purchase line and retain photographs, software information, test results and accessory records. A complete baseline helps maintenance teams identify the correct spare or expansion item without relying on appearance or an abbreviated family name.
